Re: FPGA development board "Icarus" for mining purpose - 2nd batch preparing.
I'd prefer them as a quiet and power cheap alternative to GPU mining.
In my "review" I wrote that the fans made noise but I have to correct this, it was only in the first hours.
I think the fans moved during transport and the blades of one fan touched the heatsink.
Now I hardly hear the fans anymore, I think it's between 10-15 db, way less then a normal pc.
After mining with Icarus for more then 2 days at Deepbit (25ms ping) my avg speed is in this range: 330-340 MH/s. (with 1.08% stales)
This should be much higher but one error is bugging me:
Quote from: log file
golden_id = 26
[FATAL] Read Miner ID ERROR:26, Script Restart
[NOTE] FPGA miner(s) initialize...
[FATAL] Read Miner ID ERROR:26, Script Restart
[NOTE] FPGA miner(s) initialize...
...and restart+initialize is taking 6-7 seconds...
this is killing for the avg speed.
But I'm quite happy with my current hashingrate considering the power usage of 20 watt.
Now my mining rig (pc+Icarus fpga) without monitor uses a total of 37 watt.
